Pepper consumption worldwide has risen fast in the last ten years. Vietnam has emerged as a major pepper producer. However, many Vietnamese farmers are struggling to maintain quality. Disease and precise crop nutrition and are becoming major limiting factors. That’s where we come in: the part that precise and balanced crop nutrition can make to yields and livelihoods.
With the support of the International Potash Institute (IPI), a research team from the Soils and Fertilizer Research Institute and the Central Highland Soils and Fertilizers Research Centre in Vietnam investigated how a better fertilizer strategy could help. They found that a regular and precise application of our Polysulphate fertilizer makes a remarkable difference.
The results show that black pepper yields of the unfertilized control in 2016 and 2017 were poor, and significantly lower than in the other treatments. The combination of 120/120 kg K 2O ha -1 of MOP/Polysulphate, respectively, gave rise to the best crop performance and to the highest yield, produce quality and profit. This treatment increased yields by 147% in 2016 and by 128% in 2017, as compared to the control.
When compared to the farmers’ practice, the advantage of Polysulphate becomes obvious: a smaller K input of 240 kg K 2O ha -1, 50% of which originated from Polysulphate, resulted in 8-14% more yield than obtained at 270 kg K 2O ha -1 applied with MOP.
